IMPROVEMENT IN GOOKINGfRANGBS;

TO ALL WHOM IT MAY CONCERN:

Be it known that 1, JOHN McCLO'SKnY, .of the city, county,jand State ofNew York, have invented a new and useful Improvementin Ranges; and I dohereby declare that the following is a full, clear, andexact descriptionthe'redfiwhich will enable othersskilled in .the art to make and use thesame, reference being bad to the accompanying drawing forming partof'thisspecifieation, in which-- Figure 1, sheet 1, is a planet a rangemade according to my invention, its cover being removed, and it beingshown separate from its hot-water cylinders.

This invention relates to ranges for culinary and heating purposes andit consists, among other things, in the constr'uetionof the'grates ofthe fire-chamber, the bottom gratehaiving curved bars, which make itconcave in one position and convex when'turned over. It consists,further, in placing vertical grates all around'the firechamber, a littledistance from its sides, so as to leave an air-space between its sidesand the vertical grates. It consists, further, in making-openings in thesides of the ovens next to the fire-chamber, and in controlling suchopenings with dampers; operated from the front of the range. It alsoconsists connecting the ovens by a hot-air chamber, extending behind theback ofthe range' Another feature is forming a hot-air space above theback part o ffthe rangefw'hich space communicates with the ovens, bymeans of a pipe that iscontrolled by a damper, said pipe leading intethe smoke-flue. It consists, further, in supplying airto supportcombustion along the whole ex tentlot each side of the bottom grate, bymeans of air-pipes led beneath the'ovens. It consists, further, inplacing movable boilers over the ovensfand below the level of the topplate of the range, which can be brought forward, and extended acrossthetop-of the fire when about to be used, their ends being supported by thewaterfhaek. A like boiler is inserted over the fire-chamber from thefront of the range. It consists, further, in dividing thewater-backinto'twoidistinct and independent'parts, and interposingbetween them an airespace, which is open to the fire-chamber, so thatthe temperature of the water in one will not beafi'ected by the other.It consists,further, in providing means for suspendingthe range from itsfour corners, to enable it to be used on shipboard. i

The letter A designates the fire chamber, which is four sided in thisexample, but it may be made of any other'shape. Itsbottom grate B hascurved bars, and is concave on one surface and convex onthe other. It issuspended hy journals D D at its heel; and front ends, and is soarranged and. fitted, thatit may be taken out of the range when thevertical grates C are lifted out, and turned 'dver when it is desiredthat itsconvex sur= face he. uppermost. Whenits convex'surfac e isturned up, the fuelthereon will have a tendency toslide down towards itsedges at bothgendsand at both sides, leaving a thinner body of fuel onthe middle parts of the grate than along' its edges, thereby moderatingthe rapidity combustion. The fire-chamber is supplied with, a verticalgrdte,'C, which may be, as in this example, one continuous grate-frame,or it may be composed of separate pieces, joined or connected afterbeing placed-in the firechamber. The yertical'grate is separated fromthe sides ofthe fire-chamber by an air-space, which extends to theash-chamber below, and is bounded above by the bottom of the water backP, which sets on the top of the vertical grate. By separating theVertical grate from the sides of the fire-chamber, a free supplyof airis allowed to have access to its sides,

which are also in part the sides of the ovens, and of the air-chamberthat connects them, and thcy'are thereby protected from too great heatof the fire, while such separation enables me to dispense withfire-brick or other protecting lining. I

. The letters E E designate ovens placed on opposite sides of thefire-chamber. They are connected at the rear by an air-chamber, F, thatextends across the back of the range The air-chamber makes a continuousoven and hot-air space about three sides of the fire-chamher', and'the'ovens may one or both be isolated from it by shoving back thedampers, hereinafter spoken of,which close the sides of the ovenstowards the fire. The inner side of each oven is open towards thefire-chamber, the opening for each bven being provided with a slidingdamper, Gr, operated by rods that pass through the front of the range.These dampers are right-angled in shape, their upper or horizontalpartsG being fitted beneath the top of the ovens, so as to close openings 6 6made therein,.through which the smoke from the broiling operations mayescape into the air-space E, formed between the ovens and the cover ofthe range. When these dampers close the ovens, the air-chamber is incommun'ic'ation with the ovens, but whenthe sides of the oven areopened, the rear ends of the dampers extend across the air-chamber F,and close. it to the ovens. The object of these openings in. the sidesof the ovens is to'enable me to use the direct heat of the fire in theovens for such operations as require the rays of heat directly from thefire. The walls of the fire-chamber are raised along all its four sides,above the level of the ovens, and of the air-chamber F, as at H, so asto form the space E between their tops and the cover of the range, intowhich the smoke and odors, when any of the broilers are used, passthrough openings 6 1) iii the tops of the ovens. These openings areclosed by the horizontal parts G of the sliding dampers G, abovementioned. When these dampers are pushed back to open the sidsof theovens, the openings 6 are also opened to allow the gases and odors toreach the discharge-'pipe'O. Th raised'partH supports the corner of therange.- This raised part H is cut away at each side of the fire-chamberfor a space suflicient to allow broilers I Ito enter the I fire-chamberfrom the air-space-above the ovens; When these boilersare moved back, asseen at th'e lofbhand side of fig 1, the openings in the raised part Hare closed by vertical pieces J, on their ends towards the fire. Whenthey are moved over the fire, they rest at each end on thewater-back P.Only one broiler I is used at a time. They are reached by uieans of apoker inserted through the boiler-holes of the range. A like broiler,I',.is provided at the front of the stove. I v

The smoke-pipe K rises through the cover of the range from a pointdirectly over a combustion-chamber, L, formed over the air-chamberE, andcommunicating with the fire-chamber by a passage, M, through which thegases from the fire enter. In this combustion-chamber these gases becomeburnt before reaching the smokepipe. The hot air from the air-space Eunder the cover of the rangepis conducted thence by a pipe, 0, into anupper air-space, N, over the back of the range, which forms awarming-chamber for warming platesand articles of food. It may havedoors in front, and in rear it is closed by the brick-work. This chamberN has a pipe, 0, that leads into thesmoke-pipe, and the pipehas adamper, P, so that one can at pleasure allow the hot air escape into thesmoke-pipe, or shut it off and confine it in the chamber N, and in theovens below. When the damper is open any odors that rise from thebroilers are carried into the smoke-pipe. The four covers of of therange'are provided with-staples a, which project through its cover, soas to receive hooked rods by which the range can be suspended from theceilingof a. ships kitchen or of a lower deck, thus enabling one to usethe range on shipboard without danger of having it overturned by themot-ions of the vessel.

The water-back of the range isseen'at P. It lines the four sides of therange, and comes down to the edges of theupright grates a c D, coveringthe spaces left between them and the ovens and air-chamber, so that theair from the ash-pit is compelled to pass through the bars of said sidegrates, and through the fuel which lies against them, into the centre ofthe fire-chamber, thereby causing the fuel to be abundantly suppliedwith air to support combustion, so that the fuel will be burned withuniformity, and that portion which is at the sides will not becomecooled by being clogged and.c hoked with ashes, as is common infire-chambers with solid sides. The water-back is divided into twoparts, each one of which is independent of the other, and has its own.watersupply and discharge pipes, so as to'fo'rrn two separatewater-backs Q Q, one of which, in this example, is extended from themiddle portion of the fire-chamber. backwards to the rear thereof, andthe other to the front, the separation consisting ofair-spaces R R,which are left open above and below, so that the gases of the fire cancirculate through them.

I Bythis construction, the temperature of the water in such division Qof the fire-back is u'nafi'eeted by the temperature of that in the otherdivision,-so that while one of the divisions supplies hotwater for thekitchen, (whbre it is liable to be needed at any hour,') and the otherdivision supplies the upper apartments of a house, the drawing away ofheated water from one will notlower the temperature of the other. Thedivisions QQ may be differently-arranged as to relative dimensions,'andas to the positions they occupy in the firechstnber from the arrangementhere shown, without departing from the principle of my invention. Thedivisions Q Q have separate induction a'nd eduction-pipes, the former, SS, which supply fresh water, being extended nearly down to the bottomsof the divisions, and-the latter, T T, which conduct away the heatedwater, merely opehing into the upper sides thereof. The hot-water pipesTT lead from the divisions Q Q of the waterback to independentwater-cylinders U V, which they enter some distance above their bottoms,as shown in g. 8, the cylinder V being enclosed byoylinder U, and thehot-water pipe thatleads to it being taken through the outer cylinder U,and across an annular air-space, W, which separates the two cylinders.These pipes, and and all the other pipes that, belong to the range andits water-apparatus, are to be properly packed and fitted -instuiiing-boxes to make steam-tight joints. Each cylinder U V has twopipes,X X, leading out of them at top, one of which for each cylinder isconnected with a pipe of suitable length, to conduct the hot water tothe .place where it is desired to draw it out, and the other pipes X,one'in' each cylinder, are for the escape of steainfand may be fittedwith compressing steam-gauge cooks for safety. The cylinders aresupplied with fresh water through the pipes Y Y, which penetrate throughtheir tops and terminate below the mouths of the hot-water pipes T. Thepipes S S which conduct fresh water to the divisionsQ Q of thewater-backs, leave the cylinders U V at their bottoms, where the waterof thewlowest temperatureis found. The annular air-space W thatseparates the two cylinders, is provided attop and bottom with pipes ZZ, one of which admits fresh air from below, and the other leadsheatedair froui its upper end, such heated air being led if desired intopipe N, it being clear that the air in the annular air-chamber W willnot only keep the temperature of the water in one cylinder from beingcooled or affected by the temperature of the water in the othercylinder, but that if a circulation of air .is permitted through it bymeans of the pipes Z the air therein will be heated somewhat by heattransmitted from the hot water in said cylinders. That pipe Z which goesinto thebot-tom cf the aircylinder W, enables me to draw off any waterwhich may leak into said air-cylinder from the adjoining watercylinders,and by means of such pipe I can ascertain it the water-cylinders remaintight. It will be observed from this construction, that the water-backof the range supplies hot water in two independent directions, and

in such a way that the temperature of the water, while in one divisionof the water back, and after it is conducted away, is not affected bythe temperature of that of the other. This principle ofmaking awater-back can be applied to other forms, of water-bacls, as, forinstance, to those that are placed only againstthe wall of thefire-chamber or against one of its sides. a

The letter O designates air-pipes, which supply air to supportcombustion along the whole length of the fire-chamber, at the sides ofand beneath the bottom grate. These pipes, in this example, extend fromthe forward part of the spaces beneath the ovens to the sides of thegrate. Their months 6 are flattened out, and they may be left open ormay be covered, as here shown by a perforated plate that will allow theair to escape freely therefrom. The flattened parts terminate justbeneath the edges of the bottom grate along their sides, and areextended to a length about equal to the length of said grate. Thewater-back rests on or comes ciose down to the top edges of the uprightgrates, and closes the air-spaces left between them and thcovens and airchamber, so that the air is compelled to pass through the said uprightgrates, thereby supplying constantly at good supply of air to supportcombustion at the four sides of the tire.

I claim as new, and desire to secure by Letters Patent- 1. Forming anair-chamber across the back of the range, in communication with both theovens of the range, substantially as described, so "as to form acontinuous oven and hot-air space along three sides of the fire-chamber.

2. I also claim the gas-combustion chamber, placed above the air-chamberand beneath the smoke-exitpip'e, substantially as described.

3. also claim'thebroilers I, one or more, arranged over the ovens, sothat they can be projected over the fire-chamber, substantially asdescribed. I

4. I also claim the bottom grate, when made in the form here shown,supported by journals at its ends, so

that it may be taken out and'turned upsidedown, thus enabling one to useit as a concave or a convex grate, substantially as described. i

' 5. Ialso claim'separating the divisions Q, Q of the water-hacks, by anair-space, so that the temperature of the Water in one will not affectthe temperature ofthe water in the other, substantially as described.

6. I also claim the inlet and outlet-air pipes in the annularair-chamber, that is placed between the watercylinders, substantially asdescribed. a

7. I also claim conducting the hot-water pipe that leads from thewater-back to the inner cylinder V, through the outer cylinder U; andacross the annular space W, substantially as described.

8. I also claim providing a range with staples 11,01 their eqivalents,for the purpose of suspending it from a. ceiling, as on shipboard,substantially as described.
